SNA gateway for channel transport

The HP DECnet SNA Gateway for Channel Transport is similar to the HP SNA Domain Gateway-CT but without the 3270 interactive access to HP applications or the TCP/IP support.

The HP DECnet SNA Gateway for Channel Transport (Gateway-CT) is a Physical Unit Type 2 (PU2) gateway that consists of a dedicated high-speed, high-capacity hardware device, the DEC ChannelServer II (DESNB), which connects directly to the IBM S/370 channel gateway and provides DECnet users access to IBM SNA mainframe systems. It supports a wide variety of access routines connecting OpenVMS and PCs (in a DECnet network) to IBM mainframes. The Gateway-CT connects directly to an IBM S/370 channel.

HP DECnet SNA gateway-CT software is down-line loaded into the DEC ChannelServer II. The HP DECnet SNA gateway management software, installed on the load host and other systems, configures and manages the Gateway-CT.

Software media and online documentation for the OpenVMS load and management host are supplied as part of the OpenVMS Alpha and VAX Software Product Libraries and Online Documentation Libraries on CD-ROM.


  • High-speed direct connection to IBM S/370 channel
  • Support for up to 1020 sessions
  • Up to 2.3 Mb/s sustained throughput
  • Supports DECnet transport to HP systems
